FOOT-SUPPORT.

Specification of Letters Patent.

Patcn'ted 0011.2, 1917.

Application filed February 1, 1917. Serial No. 145,857.

To all whom iii may concern:

Be it known that I, SEBASTIAN FERRIGNO, a citizen of -the United States, and a resi-- dent of the borough of Brooklyn, county of Kings, city and State of New 1 York", have invented certain new and useful 1mprove ments in Foot-Supports, of which the following is a specification. 7

My invention relates to means for sup porting the foot during the operations of boot or shoe polishing, blacking or the like, and is designed to afford simple but effective clutch mechanism whereby the foot gear may be conveniently and quickly socured in position or released therefrom, as hereinafter fully set forththe invention consisting in the specific construction and arrangement of parts described and claimed, and the distinctive feature being the use of telescopic'screws for effecting the manipulation of the clamp jaws, whereby all are moved simultaneously.

In the accompanying drawings,

Figure 1, is a side elevation of a foot rest embodying the essential features of my invention Fig. 2, is a section taken upon plane of line 22, Fig. 1, and looking upward toward the under side of the foot plate, this figure also including views of the upper sides of the clamp members, detached from the foot plate.

The inclined foot plate A, forms the upper extremity of a standard A, of any desired or suitable construction, and which is bolted to the floor or other appropriate support B. The foot plate A,may be formed with a heel gage or shoulder a, to aid in positioning the boot or shoe on said foot plate in proper relation to the clamping mechanism.

H, H, are the heel clamps, and S, S, the sole clamps.

Eachclamp-member is formed with a slot representing approximately the arc of a circle, the curve being reversed in each pair. Thus the heel-clamps H, H, are formed with oppositel inclined slots 71,, it, while the soleclamps S, are similarly formed with oppositely inclined slots 8, s. The heelclamps H, H, are movably supported on the under side of the foot plate A, by means of headed screws h, h, the shanks of which pass through said slots 72., h, and form fulcrum posts for the said clamp-members H, H, while the heads of the screws constitute flanges upon which said clamp-members are slidably suspended. In like manner'the soleclamping members S,;S, are supported upon the under side of the foot plate A, by headed screws 8, s, the shanks of which pass through the slots -8, s, forming fulcrum posts, while the heads perform the function of rests for the under sides of said clampmembers S. S.

The'outer end of each heel-clamp H, is formed with an rip-turned jaw k extending above the upper surface of the foot plate A, while its inner end is formed with a hole it to accommodate the head of a screw it, (see Fig. 1) by which the heel clamp H, is pivotally connected with the traveling nut block N, on the heel screw H. In corresponding manner the outer ends of each sole-clamp S, is formed with a jaw 8 projecting above the foot plate A, and with a hole 8 at its inner end for the accommodation of the head of a screw 8, (see Fig. 1) by which the sole clamp is pivotally connected with the traveling nut N, on the sole screw S.

The inner end of the sole screw S, is hollow and is formed with a female screw thread. for the reception of the male thread of the heel screw H,the peripheral thread of the heel screw H, and the internal thread of the sole screw S, being reversed in inclination as related to the thread on the periphery of said sole screw S, so that when the lat ter is turned axially by means of its handle S, or equivalent means, in either direction, and either the heel jaw k or the sole jaw s meets with even slight contactual resistance, the heel screw H, will be caused to rotate, and hence the nuts N, N, may be made to advance toward or recede from each other by the proper manipulation of the handle S.

It will be understood that the screw S may be caused to advance or recede on the screw H if the resistance between said screws is less than the resistance between eitiier of the screws and the corresponding nu The outer portion of the heel screw H, rests loosely in a guide sleeve a, formed for its lateral support in the standard A, and a similar guide sleeve a, is formed in said standard A, for the lateral support of the shank of the sole screw S,--both screws being free to move longitudinally through said supporting guide sleeves a, a

The telescoping of the two screws H, S, is an important factor in attaining a compact and effective construction and arrangement of parts whereby I am enabled to sumultaneously and quickly, and conveniently apply or retract both heel and sole clamps by the simple manipulation of a single part,-the handle S,it being understood that the motion imparted to the nuts N, N, by their respective screws is utilized to'swing the clamping members H, S, on their respective fulcrum post (i. 6; the shanks of the screws 71/, s) so as to bring the jaws 72, 3 into or out of commission, as desired.

What I claim as my invention and desire tosecure by Letters Patent is,

In a foot support of the character designated, the combination with the foot plate of heel and sole clamps pivotally supported on the under side thereof, traveling nuts pivotally connected with said clamps, and screws upon which said' traveling nuts are mounted, said screws telescopically engaging and threaded the one with the other, and means for manipulating said screws to advance or retract the clamps.
